Tratamiento de las fracturas complejas del fémur: nuestra experiencia con el clavo de Brooker-Wills

1996

Se estudian 26 casos de fracturas de fémur tratadas con clavo de Brooker-Wills. De ellas, 22 fueron cerradas y 4 abiertas. El trazo de fractura fue simple en 8 casos y con cominución en 18. El tipo de montaje realizado fue dinámico, con encerrojado distal, en 13 casos (50%) y estático en 12 (46%). En un caso no se practicó ninguna clase de bloqueo. En 5 pacientes (19%) ocurrió alguna complicación peroperatoria relacionada con la técnica. Eos resultados obtenidos valorados según los criterios de Thoresen han sido: 17 excelentes (65%), 6 buenos (23%), 2 regulares (8%) y 1 malo (4%). Hubo una rotura del clavo relacionada con una pseudoartosis. En nuestra experiencia el clavo de Brooker-Wills s…

An interlaboratory study as useful tool for proficiency testing of chemical oxygen demand measurements using solid substrates and liquid samples with…

2009

In 2008, the first Proficiency Testing Scheme of Chemical Oxygen Demand (1stCOD-PTADG) was conducted to assess the results obtained for different research groups whose field work is mainly anaerobic digestion. This study was performed using four samples, two solid samples as raw materials and two solid samples to prepare high concentration suspended solid solutions. Invitations were sent to a large number of laboratories, mainly to anaerobic digestion research groups. Finally, thirty labs from sixteen countries agreed to participate, but for different reasons four participants could not send any data. In total, twenty-six results were reported to the COD-PT coordinator. This study showed th…
